RAlLWAY-SEMAPHORE, 80C. 0

SPECIFICATION forming part of Letters Application filed July 24,1900.

T0 alt whom it may concern:

Be it known that I, WILLIAM DUNHAM FAR- REN, a citizen of the UnitedStates, residing at Danville, in the county of Contra Costa, State ofOalifornia,have invented a new and useful Railway-Semaphore, of whichthe following is a specification.

This invention relates to improvements in railway-semaphores. Itsobjects are to simplify, cheapen, and generally improve the constructionof such devices, to render them durable, automatic, and reliable inoperation, to give three separate movements or positions of the onesemaphore-arm, and by the agency of red, green, and clear disks toindicate the same positions at night. 4

With these objects in View my invention consists of improvedconstruction, arrangement, and combination of parts composing a signalof this class, which will be hereinafter fully described and afterwardspecifically pointed out in the appended claim.

In order to enable others skilled in the art to which my invention mostnearly appertains to make and use the same, I will now proceed todescribe its construction and operation, reference being had to theaccompa-. nying drawings, forming apart of this specification, of whichFigure 1 is a side view of myimprovement, showing the several positionsof one of the arms in dotted-lines. Fig. 2 is a plan view, the arm beingin an extended position. Fig. 3 is a detail vertical section of theupper end of the post, showing the manner of operating the lamp.

In constructing a signal in accordance with my improvement I employ ahollow post A, having its upper end terminating in a hood or case a,which is provided with openings through which the light' shines. In theupper portion of the hood is journaled a horizontal shaft to, upon theouter end of which is secured the semaphore-arms B and 0, each having aseries of apertures b and 0, respectively, which are adapted to bebrought into register with the opening upon either side of the hood. Theouter ends of the arms are provided with the usual semaphore-boards Band C, while their opposite ends are provided withcounterbalance-weights, as shown at B Patent N0. 704,015, dated July 8,1902.

Serial No. 24,674. (No model.)

and C Each arm is provided with a vertically-extending arm or rod 12 andc, to which is attached cords, whose opposite ends are connected tocranked leverand by which the arms are raised or lowered.

The'lamp or lantern F is adapted to operate within the post, and inorder to provide a simple means for raising it I attach to the bail ofthe lamp a cord G, which is passed up over the shaft a and then carrieddown to within easy reach of the operator, when it is securely fastenedwithin the post.

In order to obtain access to the lamp, 1 provide the lower end of thepost with a door A and the upper end of the post is preferably providedwith guides Ai'whioh may be socured in any suitable manner.

The particular advantage of arranging the arms as described is to enablethe operator to easilyand positively display the following signs: first,a horizontal position, meaning to stop; second, when the arms arearranged upon an angle of forty-five degrees means to slow down,caution, block or track 00- cupied, while the third position, in whichthe arm hangs perfectly vertical, indicates a clear track.

The arms may be painted red and green, as usual, while the apertures areprovided with similar-colored lines in order to make the signalsdiscernible at night.

From the foregoing the simplicity and advantage of my improvement willbe readily apparent, and it will also be observed that the arms by onemovement of either lines will be operated simultaneously, thus renderingthe signal discernible from either side.

Having fully described my invention,-what I claim as new, and desire tosecure by Letters Patentof the United States, is-

The combination of a hollow post whose upper end terminates in anenlarged hoodsection and whose opposite faces are provided withapertures, a shaft journaled in the said hood and having its endsprojecting through the hood, semaphore-armssecured-to the ends of theshaft, the said arms having a series of openings arranged intermediateits ends, one end. of the arm having a counterbalanceweight securedthereto, rods projecting from the arms, cords connected to the rods foroperating the arms, a lantern arranged within the hood and having a cordconnected thereto which passes up over and around the said shaft andsuspends the lantern in an elevated In testimony whereof I have signedmy name to this specification in the presence of two subscribingwitnesses.
